Magnavox PTV Mod.-FP5210W103 CH.-PTV 615-AH01 Mfd.-1994 Problem....No HV..?
Replaced FLYBACK (483514067128) & Q906 HV-output-xsistor (483513047771) (2SD1556). Now I have CRT fills back and when checking HV at lead coming out of Fly while disconnected from HV block/divider with neon light checker it shows HV at power up then gone. I don't know if this is normal for this unit, but with the older direct view units you could do this test and have continuous HV from fly which would let you know HV block/divider was bad. **Being that i now have HV only momentarily is there another way to confirm the HV block/divider is defective before i order. Also HV block/divider may have been replaced once before because it has a Sanyo sticker with-#-(220709-1) but looks as original as rest of unit, would Mag use a Sanyo part such as this at original manufacturing...??? And last, would anyone have a print showing value of R925, it's in the area of Fly & Q906 HV output and has been running hot enough to totally discolor and slight crumbling. Thanks to everyone in our Group. I have gathered allot of helpful info, not just from my problems but the problems and responses of everyone.

Reply�to: [EMAIL PROTECTED] (ELECTRONICS PROFESSIONALS LIST) ================================= Magnavox PTV Mod.-FP5210W103 CH.-PTV 615-AH01 Mfd.-1994 Problem....No HV..? Above unit has 132vdc B+ to collector of HOT & -.35vdc on base. When I disconnect anode & focus lead from fly to HV block, shouldn't I have HV from fly (because I don't) if HV block is bad...??? Unless I have bad fly...???
